Using the System Generator (SYSGEN)

SYSGEN Command Syntax

Commands can be classified as either command only or command with parameters(s). Commands with

parameters can be specified in one of the following ways:

positional parameters

keyword parameters

options

NOTE The command structure established by SYSGEN enables the user to select the manner in

which parameters accompany the command.

Positional parameters are assigned a position in the parameter sequence. Separate parameters by semicolons

or blanks, or exclude them by using consecutive semicolons. Enclose subparameters and repeated parameters

in parentheses, and separate them by commas or blanks.

A subparameter can be either strings or numeric values separated by blanks or commas. Enclose them in

parentheses if more than one is present. Always specify subparameters by fixed position within the

subparameter list. You can omit subparameters by entering consecutive commas.

A repeated parameter is a single parameter value that can be repeated an arbitrary number of times.

Separate parameters by commas or blanks, and enclose them in parentheses () if more than one is present.

Halting SYSGEN Command Actions

Entering CTRL Y stops listings or cancels partially entered SYSGEN commands.

Issue

CTRL Y at any point in SYSGEN. SYSGEN terminates the current action and returns its prompt. If you

enter

CTRL Y while SYSGEN is generating a boot tape, you have the option of terminating or continuing the

tape generation process.

CTRL Y is effective if the SYSGEN output and input has not been redirected and if SYSGEN is being run from

a session.

Specifying the Base Group

When altering or viewing a configuration through SYSGEN, you must first select the configuration group for

the operation. Select this basegroup by using the basegroup parameter or the BASEGROUP command.

You can specify the group only from the global module in SYSGEN, but you can accomplish this in two ways.

You can use the basegroup optional parameter in the SYSGEN command line:

:SYSGEN[basegroup][,newgroup][,inputfile]

[,outputfile]
